Do not clean Atmospheric Pressure
Demonstator. The powdery residue helps
illustrate that the effect does not depend
on the surface being clean.
Atmospheric Pressure Demonstrator must
be stored on flat surface.
Equipment
Included:
• Atmospheric Pressure Demonstrator
Introduction
The PASCO ME-8966 Atmospheric Pressure
Demonstrator facilitates teaching the concept of the force
of atmospheric pressure. A partial vacuum forms under
the Atmospheric Pressure Demonstrator when it is placed
on a smooth, flat surface and pulled straight upward with
the handle. The pressure differential that is created
prevents the removal of the Atmospheric Pressure
Demonstrator from the flat surface. A heavy board or
box can be lifted to further dramatize the force of
atmospheric pressure.
Do not attempt to lift fragile or breakable
objects such as a glass plate.
Do not use sealants with the
Atmospheric Pressure Demonstrator.
